2) one of the nicknames that lord infamous (the well-known memphis rapper) uses in his music
for both; listen to "I'm Losing It" by Lord Infamous off the Tear Da Club Up Thug's album CrazyNDaLazDayz (intro is a clip from the movie)- "you think you can catch keiser soze? you think a guy like that comes this close to getting caught and sticks his head out? if he comes up for anything it'll be to get rid of me, after that my guess is you'll never hear from me again"

Get the keiser soze mug.
a girl who starts talking to a guy at a bar then proceeds to get so drunk that when she gets up to either go to the bathroom or get another drink she forgets who she was talking too. leaving the guy dumbfounded and wondering where she went.
i was talking to this girl last night and she pulled a keiser soze on me. she went to the bathroom and just like that poof she was gone.
